Have you given up sowing good seed?
In the Bible, the common occupation of sowing seed is frequently used as a symbol of witnessing for the Lord. Unlike an actual farmer, however, Christian seed-sowers are to engage in their occupation perpetually, day after day, morning and evening, everywhere they go. "Cast thy bread upon the waters," the wise preacher said, "for thou shalt find it after many days" (Ecclesiastes 11:1). The sowing is often difficult, but is necessary before the fruit can grow, and the promise is that "they that sow in tears shall reap in joy" (Psalm 126:5).
Often others may reap the fruit of our seed-sowing labors (or we may reap the fruit of theirs), but that is all right, for Christ Himself said that "One soweth, and another reapeth" so that "both he that soweth and he that reapeth may rejoice together" (John 4:37, 36). Paul said, "I have planted, Apollos watered; but God gave the increase" (1 Corinthians 3:6).
Some seed, faithfully sown, may not seem to grow at all. In Christ's great parable of the sower, much of the seed fell by the wayside or on rocky or weed-infested ground, but "other fell into good ground, and brought forth fruit" (Matthew 13:8). It is our job to be sure that the seed we sow is good seed, wherever we go--by word, by life, by giving, by listening, by our very presence, by praying, by whatever we say or do or even think--and then to trust God to bring forth the fruit according to His own perfect will.
"Blessed are ye that sow beside all waters" (Isaiah 32:20). Therefore, "in the morning sow thy seed, and in the evening," and God will prosper our faithfulness in His own good way and time.
